CAN TOPPING AND WIPING MACHINE.

SIECiFICATION forming part of Letters Patent No. 652,581, dated June 26,1900.

Application filed March 1, 1900. Serial No. 6,965. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES H. AYARS, a citizen of the United States,residing at Salem, in the county of Salem and State of New Jersey, haveinvented certain new and useful Improvements in Can Topping and W'ipingMa chines, of which the following is a specification.

My invention relates to certain improvements in can topping and wipingmachinery, the object of the invention being to provide automaticmechanism for intermittently conveying unsealed cans previously filledwith vegetables or fruit to a plugger, which pushes the contents downfrom the mouth of the can. The can is then moved beneath a brush, whichhas its front edge recessed or hollowed out and which brushes any of thecontents which may have been forced by the plugger out and upon the canstop back into the can, and then to a reamer or topper, which removes thecontents of the can from contact with the edge of the cans mouth toprevent chilling of the solder by which the cap is secured. The can thenpasses successively beneath one stationary and four revolving brushes,which wipe all moisture from the top of the can and dry it preparatoryto applying the cap.

Referring to the accompanying drawings, Figure 1 is a side elevation ofthe machine.- Fig. 2 is a plan View of the belt-driven pluleys at thetop of the machine. Fig. 3 is an enlarged sectional view of my reamer.Fig. 4 is an enlarged plan View of the recessed brush and several cansbeneath.

A is the frame of the machine, which frame is provided with suitablebearings and guides for the moving parts.

B is a vertically-movable table with horizontal guide-rails ct on alongeach side and supported by two spiral springs Z) Z), through which passvertical guide-rods c c, said rods having their upper ends fastened tothe under side of the table B, their lower ends being free to movevertically in the guides d d, which are fastened to the frame A. A loosecollar (designated on one rod 6 and on the other e) is placed upon eachguide-rod below the said spiral spring and over the forked ends of thetwo levers ff, extending from the center in opposite directions, and acollar e e is securely fastened to each of said rods just below theforked end of said lever. The said two levers f f are pivoted at g g,their other ends at the center being hinged at h h to two shortlinkst't", which are in turn hinged to one end of the leverj, whoseother end is hinged at k to a bracket on the frame. The said lever has aroller Z mounted near its center, upon which the cam m bears.

The horizontal shaft 0 supports and r0- tates the three cams on m m andis driven by the gear at, which in turn is driven by the pinion n,mounted upon the shaft 0, which shaft also drives the bevel-gears n nand is driven by the wheel at". The shaft C' supports the lever P, whichis vibrated by the cam on coming in contact with the roller Z and springb transmitting an intermittent lateral motion to the horizontally-guidedcan-pusher bar D through the lever f and adjustingscrew E. The cam onacts upon a bar j, which at one end is hinged to the bracket 7.: on theframe and at the other end to the vertical rod 0, which operates thereamer, as will presently be described. The vertical shaft 0 driven bythe said bevel-gear n drives a pulley P at the top of the machine,fromwhich an endless belt S drivesall the other pulleys P P P P P P, thebelt being wound in the direction shown in Fig. 2. The pulley P drivesthe reamer. Pulleys P P P P drive revolving brushes r r 7' r Pulley P isan idle pulley for tightening the belt.

r is a stationary brush whose front edge is recessed, preferably into Vshape, and which is supported by adjustable brackets fastened to thetable B, and r is another stationary brush similarly supported.

2) is a plugger fastened to the top part of the frame of the machine anddepending downward.

Referring to Fig. 3, the reamer consists of a vertical tube q, driven bythepulley P, which tube supports and rotates the pivoted plug .9,projecting from the bottom. A second tube q is within the upper part ofthe tube (1 and is revolved with the tube g by engaging with the upperend of the plugs, which projects upward between the lugs t t within saidinner tube. The inner tube is vertically movable and is depressed by theaction of the cam m through the bar 3, vertical rod 0,

and lever 0', which is pivoted to the bracket 0 A rigid bracket todepends from the top of the frame and has on its bottom a disk 10,preferably of rubber, with a central hole. It also has four smalltapered lugs or pins y to center the can-top. The reamer 3 projects downthrough the disk 10, against which the top of the can z presses whilethe operation of reaming is going on.

The operation is as follows: Unsealed cans, filled with fruit orvegetables, being placed upon the table 13 at the end 1) are shovedalong the table at each revolution of shaft 0 a distance equal to thediameter of the can. Cans are placed upon the table at the rate of onecan for every revolution. of shaft C by means of the shover D. To makethe operation clear, take the case of a single can and follow thesuccessive operations: The shaft 0, revolving right handed the cam m,first acts, causing the can-pusher bar to shove the can forward.Supposing the can to be now under the pluggerp,the cam m,actin g in itsturn, raises the table B and can, causing the plugger to compress thecontents of the can, forcing the contents down from the mouth. It is tobe understood that while the table is in its elevated position othercans which have preceded the one under discussion are being reamed andbrushed at the same time that the one under consideration is beingplugged. After a can has been plugged the table is lowered by the cam mhaving completed its operation. By the continuous rotation of shaft 0cam m is again brought into operation, and after two cycles of operationthe can,having passed under the recessed brush 1", arrives under theream er 8. Then as the table again rises by the action of cam m the canis pressed up in contact with the rub-. ber disk 10. The cam m now acts,depressing the inner tube q of the reamer through the tinuouslyrotating, it removes the contents of the can from contact with the topof the same around the edge of the mouth. Cam m having now passed by,the inner tube q rises, and the reamer resumes its normal position. Thecan next passes by successive stages beneath the stationary brush "1'and each rotating brush in turn. The distance between each rotatingbrush and the plugger and reamer is a multiple of the diameter of thecan and is also adjustable to suit cans of different diameters. Theaction of the springs 19 b is chiefly to allow for inequality in heightof cans, thus compressing the springs instead of crushing the can.

Having thus described myinvention, what I claim as-new, and desire tosecure by Letters Patent, is-

1. In a canning-machine the combination spiral spring around each ofsaid vertical rods and its lower end resting on said loose collar; andtwo levers, f, f, below the table, each lever having one end below adifferent one of said loose collars.

3. In a canning-machine, the combination of a frame, revoluble brushesmounted in said frame, a vertically-movable can-supporting tableunderneath said brushes,means for raising said table, and a yieldingconnection between said means and the table.
